Man error about CentOS6

1) For commands that cannot be found, man will report an error:

[Jing @ CentOS locale] $ man abc

Cannot open the message catalog "man" for locale "zh_CN.UTF-8"

(NLSPATH = "/usr/share/locale/% l/LC_MESSAGES/% N ")

 

 

No manual entry for abc

[Jing @ CentOS locale] $

 

 

 

 

2) After reading it with strace, we found that at the end:
